摘要

Spinel ferrites are widely studied for their distinctive physical properties that enable diverse applications. This investigation dives into the impact of Cd substitution on the functional properties of Ni0.8-xCo0.2CdxFe2O4 (NCCF, x = 0.05–0.20) ferrites. The samples were synthesised using the solid-state reaction route. Structural analysis was performed via X-ray diffraction, confirming the formation of a single-phase cubic spinel structure and revealing a systematic increment in lattice parameter with increased Cd content. The FESEM and Raman spectra also support the observations. Magnetic measurement demonstrated that Cd incorporation significantly alters the superexchange interactions between A- and B-site cations, resulting in notable changes in magnetic ordering and magnetization behaviour. These findings suggest that Cd substitution offers a viable approach to tailor the properties of Ni-Co ferrites for various applications.
